Every major city has a camera store for geeks, the truly serious - as opposed to a chain store - and you'll usually find some very knowledgeable people there who would immediately take your price range and rattle it through their heads for some suggestions. Talk is cheap and that might be a place to start as well. You could probably even just call them for help if you can't visit.
Hope the above gets you started. Others probably have some suggestions for you.
